Countercurrent washing, large capacity and high washing efficiency;
Small area taken, reasonable structure and low cost of operation and maintenance.

Xinhai washing thickener includes two layers washing thickener and three layers washing thickener. Taking the three layers washing thickener as an example. The pulp is fed by a feeding tube, and the pulp that settles freely in the rake area is further concentrated by the pressure of the scraper blade, gradually scraped towards the center of the pond, then enters the next layer pond through the mudding slot. The clear water is entered into the lowest layer for washing the material through the distribution box, the bottom of overflow is returned to the upper layer for washing the material through the distribution box. The overflow of the first layer is discharged through the downflow weir, and the material after two times of washing is discharged through the bottom.

The gold dressing plant in African Tanzania contracted by Xinhai originally chose two ordinary gold washing machine for backwashing, but space is limited due to the replacement of many equipment, so the customer adopted Xinhai double (three layers) washing thickener, the washing effect and production efficiency only have small difference, but the area is much smaller, which solved the problem of space, and the production cost also is under control.
